HEADSET REDUCERS 1 1/4- 1 1/8
would be the best bet, I.D distribution as well as BETD do them.
i have a 1 1/4 judy crown that i can sell you if its any good.
A question though, i don't think kona supplied the DH frame with a purple swing arm though, i thought it was a grey colour anodised...
may be wrong..
i think Windwave still have rear shocks for these, coil only though.
i used to have the old hope technology test bike from years ago, that i bought from them..
